ROTARY TURBlNE-ENGIINE.

SPECIFICATION forming part of Letters Patent No. 755,481, dated March 22, 1904.

Application led December l2, 1903. Serial No. 184,855. (No model.)

To all w/toml t may concern:

Beit known that I, GUsTAv GRIEscHn, a citizen of the United States, residing at Berkeley, kin the county of Alameda and State of California, have invented new and useful Improvements in Rotary Turbine-Engines, of which the following is a specication.

My invention relates to a device which I call a rotary turbine-engine.

It consists of a drum having spirally-disposed grooves or passages extending around it from the center toward each end and means for admitting an elastic medium under pressure either to pass through the said spiral passages from the center outwardlyto drive in one direction or from the ends toward the center to reverse the motion of the apparatus. In conjunction with this drum is a casing within which it is revoluble and valves so disposed as to admit the propelling medium either from the center or the ends and to exhaust it from lthe opposite ends of the passages from the point at which it is admitted. These spiral passages are peculiarly constructed so as to permit an expansible action of the medium and both direct and reactionary pressure to propel the drum.

My invention also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure l is a side elevation and partial longitudinal section of my apparatus. Fig. 2 is an exterior view of the drum,`showing the spiral passages. Fig. 3 fis a transverse section of the valve and valve-casing.- Fig. 4 is a transverse section of the apparatus, taken through y y of Fig. 1. Fig. 5 is a similar section taken through @c m of Fig. l.

As shown in the drawings, A is an exterior case within which the drum B is revoluble. I have shown the drum as made with a central web, and the periphery of the drum forms flanges which extend outwardly in either direction from the web, as shown at 2.

The heads 3, which are secured to the ends of the casing, are fitted to enter the depressions or cavities formed by the flanges of the drum extending outwardly from the web, and these heads also carry journal-boxes suitable for the shaft 4, to which the drum is secured and through which power and motion may be transmitted when the drum is revolved. The drum lits revolubly but substantially gastight within the case A, and around its periphery are three grooves or channels-the central one (shown at 5) and two end ones, as at 6. Connecting these grooves are spiral passages 7, which pass around the periphery of the cylinder, as shown plainly in Fig. 2, the inner ends connecting with the groove 5 and the outer ends, respectively, with the grooves 6, the spirals being right and left from the center outwardly. These passages may be made in any suitable or desired shape. In the present case I have shown them as formed with buckets connecting with each other and in zigzag lines upon each side of y the center of the spiral passage, these buckets connecting with each other, lso that when the iiuid under pressure is admitted it acts first by impact against the forward sides of the buckets and afterward by a reactionary force as it passes on through the passages, expanding as it goes until it reaches the discharge.

It will be manifest that when the fluid is admitted at the center to enter the channel 5 it will pass outwardly, respectively right and left around the drum, through the buckets 7 until it reaches the end channels 6 andA escapes therefrom through suitably-constructed ports and valve-openings, asv will be hereinafter described. If the iiuid is admitted to the end channels, it then passes in the opposite direction through the buckets around the drum and is discharged through the central channel 5 and thence through ports to a dischargeopening, this movement of the iuid acting to reverse the movement of the drum., and motion may be transmitted from the drum in either direction by means ofthe shaft 4.`

In order to reverse the movement of the Huid and the consequent motion of the drum, I have shown a central valve 8 and end valves 9. These valves are revoluble in casings, as

IOO

valve 8 has connecting inlet-pipes 12 and the exhaust-pipes 13, this valve controlling the central passage to either admit the Huid, which will be exhausted from the outer ends, or it may serve to exhaust the fluid which has been admitted from the outer ends, as previously described. rlhe valves at the outer ends have similar chambers, as at 11, each of these valves having connected with it an inlet-passage, as at 14, and an exhaust-passage, as at 15. These valves 8 and 9 have stems projecting outwardly through stufling-boxes in the cases 10, as shown at 16, and upon the outer ends of these stems are crank-arms 17, which are connected together by a rod 18, extending across and connecting with each crank.

A lever 19 serves to move the connectingrod and the crank-arms simultaneously, so that when this lever is moved in one direction-as, for instance, to the right-the central inlet-passages will -be opened and the exhaust at the end of the drum. By moving the lever to the left the end inlets will be opened and the central exhaust. If the lever be left at a central position substantially vertical, as shown, the fluid will be cut off and the engine remain stationary.

Although but one spiral is shown upon the drum on each side of the central groove, it will be understood that there may be as many of these spirally-disposed chambers connecting the outer and inner grooves of the drum as the surface of the drum will admit, and `the elastic fluid will be admitted to and exhausted from each set and all of said charnbers simultaneously during the operation of the machine.

Having thus described my invention, whatI claim, and desire to secure by Letters Patent, 1s- 1. A rotary turbine comprising a cylindrical drum, la journaled shaft upon which it is mounted, spirally disposed and connected chambers formed upon the periphery and extending in right and left directions from the central portion of said drum, a cylindrical casing within which the drum is revoluble, means for delivering an elastic fluid under pressure into one end of the spiral chamber and means for exhausting the Huid from the opposite end.

2. A rotary turbine-engine comprising a cylindrical drum mounted upon a centrallyjournaled shaft, spirally-disposed connected chambers extending around the drum in right and left directions from the central portion thereof, grooves or channels with which opposite ends of said chambers connect,a cylindrical casing within which the drum fits and is revoluble, valves by which an elastic fluid under pressure may be admitted to the grooves to pass through the chambers and valves through which the uid'may be exhausted after completing its work.

3.,A rotary turbine-engine comprising a cylindrical drum, a journaled shaft upon which it is mounted and turnable, grooves or chan-' nels formed around the center and ends of said drum, spirally-disposed and connected expansion-chambers'having their inner ends connected with the central groove and having their convolutions around the drum in opposite directions from the center to the ends, said spirals having their outer ends connected with the outermost grooves, an inclosing casing within which the drum is revoluble and inlet and outlet valves connecting with the circumferential grooves of the drum.
